Solve the system. 3x - 2y = 12 and 3x - 3y = -2
Answer:
x = 4 + -0.6666666667y x = 1 + yStep-by-step explanation:
Simplifying
3x + 2y = 12
Solving
3x + 2y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
3x + 2y + -2y = 12 + -2y
Combine like terms: 2y + -2y = 0
3x + 0 = 12 + -2y
3x = 12 + -2y
Divide each side by '3'.
x = 4 + -0.6666666667y
Simplifying
x = 4 + -0.6666666667y
Simplifying
3x + -3y = 3
Solving
3x + -3y = 3
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
3x + -3y + 3y = 3 + 3y
Combine like terms: -3y + 3y = 0
3x + 0 = 3 + 3y
3x = 3 + 3y
Divide each side by '3'.
x = 1 + y
Simplifying
x = 1 + y

Answer:
£16 : £144
Step-by-step explanation:
Sum the parts of the ratio, 1 + 9 = 10 parts

Mr. Lopez wrote the equation 32 g + 8 g minus 10 g = 150 on the board. Four students explained how to solve for g.
Alyssa: “I added 32 and 8 to get 40, subtracted 10 to get 30, and then subtracted 30 from 150 to find the value of g, which is 120.”
Rahul: “I added 32, 8, and 10 to get 50, and then I subtracted 150 to find the value of g, which is –100.”
Toni: “I subtracted 18 from 32 to get 14, which I then divided into 150 to find the value of g, which is 10 and StartFraction 5 Over 7 EndFraction.”
Wilhem: “I added 32 and 8 to get 40, subtracted 10 to get 30, and then divided both sides by 30 to find the value of g, which is 5.”
Which student’s work is correct?
Alyssa

Mark this and return Save and Exit Next
Answer:
Willhem
Step-by-step explanation:
The given equation is
Step 1 : Add 32g and 8g.
Step 2: Subtract 10 from 40.
Step 3: Divide both sides by 30, find the value of g.
The value of g is 5.
Therefore, Wilhem is correct.

Answer: -9/4
Step-by-step explanation:
First you subtract 7/2 from both sides of the equation
3x + 7/2 - 7/2= x - 1 - 7/2
Next what you do is simplify one you add 3 + 7/2 which is 9/2
Then you subtract X from both sides of the equation
3x - x = x - 9/2 - x
combine the terms
2x = -9/2
divide both sides of the equation by the same term
2x/2 = 9/2 / 2
cancel the terms and divide the numbers
x=-9/4

Step-by-step explanation:
Jackson went to a store that was selling everything at 25% off! The price of a coat that he bought was $34.50 after taking off the discount. What was the original price of the coat?
Given:
The price of coat after discount of 25% is $34.50.
To find:
The original price of the coat.
Solution:
Let x be the original price of the coat.
Price of coat after discount = Original price - 25% of original price
On substituting the values, we get
[tex]34.50=x-\dfrac{25}{100}\times x[/tex]
[tex]34.50=x-0.25x[/tex]
[tex]34.50=0.75x[/tex]
Divide both sides by 0.75.
[tex]\dfrac{34.50}{0.75}=x[/tex]
[tex]46=x[/tex]
Therefore, the original price of the coat is $46.

I don't really understand it but, i did 80% divided by 10 but it would be $0.08 and i don't think it would be that so i did 10 divided by 80 and it came out as $12.05.
